Melamine Superplasticizer (SMF Plasticizer)
CAS Number: 25036-13-9
Sulfonated melamine formaldehyde (SMF) condensate is a high-performance concrete plasticizer offering water reduction rates of 20–25% with minimal retardation. It produces light-colored concrete suitable for architectural applications and is especially valued in floor screeds and industrial flooring where appearance and early strength are critical. SMF is compatible with gypsum-based systems as well as Portland cement.
